IMPROVEMENT IN ZINC-BOARDS FOR STOVES.

Specification forming part of Letters Patent No. 127,310, dated May28,1872.

SPECIFICATION.

To whom it may concern:

Be it known that I, WILLIAM S. GoTTEELL, of Chicago, in the county ofCook and State of Illinois, have invented certain new and usefulImprovements in Zinc-Boards, of which the following is a full, clear,and exact description, which will enable others skilled in the art towhich my invention appertains to make and use the same, reference beinghad to the accompanying drawing forming a part of this specification, inwhich- Figure l represents a top or plan View of my improved zinc-board;Fig. 2, a central vertical sectional view of the same 5 and Fig. 3, alike view, enlarged.

I am aware that sheets or plates of zinc, or other suitable metal, haveheretofore been used, either alone or in combination with wood, for thepurpose of protecting the flooring, carpets, and walls of buildings fromthe heat of stoves. Zinc, or other metal, when used alone, frequentlybecomes sufficiently heated to injure the parts in Contact with it, anda moderate heat of the metal, when long used in the same place, has beenfound to injure carpets or other materials easily injured, such asoilcloth. Wood has been used, in combination with metallic plates orsheets, for the purpose of avoiding these injurious results, the woodbeing interposed between the metal and the material sought to beprotected. The objectionable features in the use of wood for thispurpose are, that the wood shrinks and warps so as to disfigure themetal, unless either prepared wood or boards of a suitable kind orconstruction are used, or unless the board is made sufiiciently thicknot to warp to any considerable degree. The boards are usually madethick for the purpose mentioned, and so that wood of a common kind maybe used without being specially prepared, or without a specialconstruction of the boards 5 but thick boards, es-

pecially when placed beneath the stove, and projecting therefromsufficiently to be serviceable for the purpose intended, areinconvenient, as a ridge is thereby formed on the floor about the stove,and this ridge is especially inconvenient about a cook-stove.

My invention has for its object the making a zine-board, so called,which will aord a sufficient protection from the heat of' the stove,andwhich will neither warp nor shrink so as to disgure the appearance ofthe board, nor be so thick as to be inconvenient, and which Will also beneat in appearance and, to that end, my invention consists in the useof' tarboard;7 paper, or pasteboard, in combination with zinc, or othersuitable metallic plates or sheets, paper or tar-board being not onlyservieeable for the purposes'mentioned, but also better non-conductor ofheat than Wood.

A, in the drawing, represents a plate or sheet of zinc, or othersuitable metal. B represents the tarboard,77 paper, or pasteboardbeneath the Zinc, and attached thereto in any suitable manner. Thezinc-board may be ot' any suitable size or `form. l

Having thus described my invention, what I claim, and desire to secureby Letters Patent, 1s-

l. The combination of plate or sheet zinc, or other suitable metal, withtar-board, paper, or pasteboard, substantially as and for the purposesspecified.

2. As a new article of manufacture, a zincboard,77 made of sheet orplate zinc, and either tar-board, paper, or pasteboard, substantially asspecified.

The foregoing specification signed by me this 19th day ot' December,1871.
